What does it mean to urge the examination officer to play this poem?

Interpretation: The Qiantang River spring tide is just like the wings of a legendary bird flapping on the water, and it is also like a hundred thousand people rushing forward, forming a huge white jade belt. The blue umbrellas of the tide-watchers echo the red flags around them, and the white waves hit the black banks, and the black and white colors flashed off each other.

How difficult it is for so many people to gather in one place. We can't go with each other to watch the Qiantang River tide and the exam. I hope the examiner can work overtime to read the exam papers. Outside the door, the scholars are stretching their necks and padding their feet, looking forward to publishing the exam results.

Original text:

Kun Peng hit three thousand Li with water, and trained a long drive of one hundred thousand men. The red flag and the green cover fade away from each other, and the black sand and white waves devour each other.

life meets ancient difficulties, and this scene and this trip have two advantages. May you smell this candle, and the white robe outside the door is like a stork.

Creative background:

Su Dongpo, then the general judge of Hangzhou, sympathized with the candidates who were eager to wait for the results, and wrote this song, urging the examiners to take exams, hoping that the examiners would burn the midnight oil to quickly approve the examination papers, so that the candidates could enjoy the Qiantang River tidal bore on August 18th with ease and pleasure.

Gongju was the local selection stage for imperial court to take the exam in feudal society, and the exam of Gongju was released on the Mid-Autumn Festival. This year, however, it was two days late, and the results were released on August 17. Needless to say, the candidates were quite anxious, so Su Shi had a job of urging the test officials.

Su Dongpo is knowledgeable, good at writing, painting and calligraphy. Yu Ci is "bold and unconstrained, and doesn't like tailoring to follow the rhythm", with rich themes and broad artistic conception. He broke through the traditional barrier of "Ci is a colorful subject" since the late Tang and Five Dynasties and the early Song Dynasty, and took poetry as his ci, creating a bold and unconstrained school, which had a great impact on later generations. There are seven episodes of Dongpo, Dongpo Ci, Dongpo Yi Zhuan, Dongpo Yuefu and so on.
